Patented May 22, 1945 UNITED STATES PATENT OFFICE I RANGE Isaac VernonBrumbaugh, St.-Louis, Mo., assignor to American Stove Company, St.Louis, Mo., a corporation of New Jersey Application September 20, 1941,Serial No. 411,737 22 Claims- (Cl. 126-39) This invention pertains toranges and more specifically to what I have termed aflushagainst-the-wall" range, and is a continuation in part of mycopending application Serial Number 162,045, entitled Ranges, whichmatured into Patent No. 2,264,657, issued December 2, 1941.

In recent years there has been a concerted endeavor to improve theappearance of kitchens and although great progress has been made rangeshave remained an unsightly piece of kitch-.

en furniture for the reason that their rear ends are positioned inseparated relationship to the kitchen wall which leaves a .space or gapwhich is particularly noticeable and objectionable as the remainingfurniture in the kitchen almost invariably is disposed with its rearends in flush abutting relationship to the wall of the room.

Althoughit might appear obvious to correct the foregoing situation ithas not been for the reason that ranges invariably discharge the .hotproducts of combustion at their rear ends and this fact together withthe heat generated by the ranges has made it dangerous to closelyassociate the rear ends of the ranges with the wall of the room or toclose in the space between the rear end of the ranges and the room wallon account of the danger from fire hazard.

I have devised a novel and improved construction which makes it possibleto safely dispose the rear end of cooking ranges in flush relationshipto the room wall so that the range as a piece of kitchen furniture willmatch and blend with the remaining kitchen furniture. Consequently, theprimary object of the invention is the provision of aflush-against-the-wall range.

In the accomplishment of the foregoing beneflcial and improved resultnovel and improved mechanical construction and arrangement is necessaryin respect to the fluing of the products of combustion of the range todischarge; provision for secondary and primary air delivery to the rangeburners, and the cooling of the chamber behind the rear end of the rangeand between it and the wall of the room, all of which are objects of theinvention and the specific nature of these will appear from thefollowing description when read in the light of the accompanyingdrawings.

In consideration of the description and drawings attention is directedto the fact that no attempt has been made to illustrate every type ormodel of cooking range although the present invention is applicable toall models and types of ranges. As illustrative of the foregoing, thereare ranges in which the entire cooking top surface is at one end of therange and the entire working or table top surface is at the other andopposite end. In such ranges the cooking top burner chamber does notextend entirely across the top of the range as it does in all of theranges illustrated in the drawings but on the contrary would lie onlybeneath the cooking top portion of the range. In such ranges it isconventional for the working or table top portion to constitute the topof the range oven. Additionally there are range models in which there isa single oven which serves the dual purpose of being a baking and a.broiling oven. Such model ranges lend themselves equally as well to theadaptation of the present invention. Also there are range models inwhich the range is supported on legs rather than on a solid base asillustrated in the accompanying drawings. Such a construction will notalter the application of the present invention to the range.

With the foregoing in mind it will be understood that the drawingsillustrate only a few forms of range constructions in combination withthe present improved invention.

Having reference now to Figs. 1 and 2 of the drawings the range hereillustrated is one of the more or less conventional types commonlyreferred to. as a "divided working top" range in that the cooking top iscentrally located and workingor table top surfaces are provided at eachside thereof. The range comprises a main body or housing at one end ofwhich behind a suitable door I is positioned a broiling oven 2 andbeneath which is a sliding utensil storage drawer 3.

At the opposite end of the range a baking oven lies behind the door 4. Acooking top burner chamber 5 extends completely throughout the lengthand depth of the range body above the ovens. In this chamber arepositioned the cooking top burners 6 beneath the cooking top grid 1 andthe chamber also lies beneath the working or table top portions 8 and 9at the opposite ends of the range. Like many ranges of this typeswinging covers l ar provided for the cooking top portion of the rangewhen the same is not in use.

The present range like practically all ranges is provided at its rearwith a splash back or splash plate I I which is a vertically disposedplate extending throughout the length of the range and as its nameimplies is for the purpose of protecting the kitchen wall against stainsor discolorations.

The range here illustrated is of the legless type in that the end wallsl2 of the range extend completely to the floor and that the front of therange likewise extends completely to the floor but. adjacent the floorlevel is provided with an inset to provide a toe space l3. Practicallyall ranges today are of the double wall insulated type and so likewiseis the present range and in Fig. 2 of the drawings the insulated rearrange wall l4 and the insulated oven top I5 are illustrated;

Although the present range provides a piece of furniture having aflush-against-the-wall appearance the rear wall of this range as well asthe splash back thereof is in separated spaced parallel relationship tothe wall I6 of the room with the result that between the wall and therear end of the wall there is a space i'lbut this space is, as willhereinafter more clearly appear, completely enclosed so as to form ofthe space a closed chamber.

Closing in the space I! is accomplished by providing the end walls l2 ofthe range with a rearwardly extending portion or flange I8 which extendsfrom the rear of the range into an abutting relationship to the roomwall and providing the. splash back plate with a top l9 and end wallswhich likewise abut the room wall. The end walls 20 of the splash backare in reality no more than an extension of the rear flanges [8 of theend walls of the range and could be made as such if it were founddesirable to do so. 0

The broiler oven burner appears at 2| and although not illustrated itwill be understood that there is a suitable burner in the baking oven.In stoves of the present day type wherein the burners are completelyenclosed for the purposes of appearance, it will be necessary to provideboth primary and secondary air. This can be accomplished in severalways. In the present instance air is provided for the burner in thebaking oven through a series of holes 22 through the rear wall of thetoe inset at the front of the range. A similar set of holes 22a areprovided to admit air beneath the range bottom 23 at the opposite end ofthe range beneath the utensil drawer 3. Air entering through theseopenings passes into the space 24 beneath the range and through openings25 into the drawer chamber 26 and from that chamber through the openings21 in the broiler oven bottom 28 into the broiling oven 2. The

rear end of the range is supported on legs 23 and consequently the rearend of the air passageway or chamber 24 and the lower end of the chamberH are in communication so that air can pass.

freely into the lower end of and upwardly in the chamber I! as clearlyindicated by arrows in Fig. 2 of the drawings. This air stream serves adual purpose as will now be explained.

' Across the back of the range adjacent the tops of the ovens thereof ahorizontally disposed and elongated flue box 30 is provided. This boxlies within the chamber l1 and at one end has communication as at 3|with the broiling oven and at 32 with the baking or cooking oven.Intermediate its length this box is provided with an opening 33 in itstop and upon the top of the box and over this opening is disposed avertically extending flue 34. The vertical flue and the horizontal fluecan have a common insulated rear wall 35 which chamber I'I enters thecooking top burner chamher 5 around the ends 38 of the horizontal fluebox 30. This provides primary and secondary air for the cooking topburner chambers and by its passage and circulation over the tops of theovens will serve as a cooling medium and thus keep down the temperatureof the working and table top surfaces 8 and 9.

The front wall of the vertical flue 34 and the splash back II areprovided with a series of louvers 39 so that the products of combustiongenerated within the baking and broiling ovens and discharging throughthe flue box 30 and vertical flue 34 will be discharged forwardly anddownwardly through the splash back and away from the room wall toprevent any staining or discoloration of the room wall.

In conformity with providing a range of pleasing appearance the gassupply pipe 4|! is concealed behind the range and within the cooking topburner chamber and is connected with a conventional manifold 4|extending across the front of the cooking top burner chamber behind thefront panel 42 thereof. At the front of the panel 42 are disposed theplurality of gas cock handles 43 for controlling the supply of fuel tothe various burners and here also is located the temperature dial orwheel 44 when the range oven is provided with thermostatic heat control.

With a range of the construction described it will be seen that theappearance of the kitchen is greatly enhanced as is also the appearanceof the range itself. Fire danger is avoided because the accumulation ofheat in the chamber I1 is prevented by a continuous circulation of acooling air stream therethrough and particularly behind the range outletflues so as to maintain a constant heat insulating medium between theseflues and the wall of the room. Primary and secondary air is providedfor all of the burners of the range and the hot products of combustionare discharged in a manner to guard against and prevent the heretoforeobjectionable discoloration of the paper or paint of the room wall.Additionally the necessity of painting or papering behind the range, ashas been necessary with ranges which are disposed in spaced relationshipto the kitchen wall, is obviated. All unsightly parts of the range suchas the gas supplying pipes are concealed as is also the cooking topportion of the range by the covers 10 when the range is not inoperation. It will be further evident that the present range willsimplify keeping the kitchen in a sanitary condition. With the old typeof range the space between it and the wall was most difllcult to get atto dust and clean and the necessity of. this with the present range isremoved.

Referring now to the slightly modified construction illustrated in Figs.3 to 5 inclusive of the drawings, the same general type of rangeappearing in Figs. 1 and 2 of the drawings is again illustrated in thatthe range is of the divided working top type with the cooking toppositioned intermediate the ends of the range.

Here the cooking top 45 is flanked with table top working portions 46and 41. There is the same broiling oven behind the door I and bakingoven behind the door 4. The ends l2 of the range extend'into flushabutting relationship to the room It and the splash back 48 has a top 49and end walls 50 which together with the extending portions it of therange end walls close in the chamber l'l behind the range. The maindifference between the range here illustrated and that appearing inFigs. 1 and 2 of the drawings resides in the fact that there are twoflues provided for the escape of the products of combustion and theseflues are not disposed behind the splash back 48 but, on the contraryare in front thereof although being behind the range proper.

By reference to Fig. 4 of the drawings it will be seen that within thecooking top burner chamber 5 there are a pair of flue boxes 5| and 52.The box 5| is above an opening 53 in the top of the broiler oven and thebox 52 above an opening 54 in the top of the. baking oven. Each of theseboxes is provided with a vertically extending flue 55 the upper open end56 of which passes through the working top portion of the range im- Inthis construction, just as in the previously described construction,there is the air chamber ll behind therange and air is supplied to theoven and cooking top burners in the manner described in respect to theFigures 1 and 2 construction'. It will be obvious that air from thechamber ll can enter (see Fig. 4 of the drawings) the cooking top burnerchamber through the space 59 between the flue boxes 5| and 52. The airwithin the chamber ll constitutes a cooling insulation between the roomwall and the rear walls 60 of the flue boxes and the splash back 48.

Figures 6 and 7 of the drawings illustrate further modifledforms of theinvention the modiflcations residing particularly in two distinctions.Here the ranges are provided with cooking top portions 8| and 62 inspaced relationship at opposite ends of the ranges while the table topworking surface 83 is positioned centrally of the length of the range.

In the Figure 6 construction the flue outlets for the ovens will liebehind the splash back at and these will discharge through an elongatedslot 65 in the front of the splash back near its upper edge. This sameslot will provide for the escape of cooling air which is circulatedthrough the chamber l'l behind the range and splash back and thus servesa dual purpose.

In the Figure 7 construction the splash back 66 is of step-likeformation having in its front a pair of slots 61 through which the hotproducts of combustion conveyed to them by the flues behind the splashback will discharge. The top 88 of the splash back is provided withspaced slots 69 for the escape of cooling air from the chamber I1 behindthe range. and splash back.

In both of these constructions the chamber behind the range iscompletely closed as clearly illustrated in these figures of thedrawings, as has been pointed out in the previously describedconstructions.

Figures 8 and 9 are illustrative of a slightly modified form of flue andthe inventive idea here illustrated could be incorporated into thepreviouesly described forms of the invention.

In these figures of the drawings there is a centrally arranged workingtop surface 10 with cooking top surfaces II and" at each side thereofand at the ends of the range. Th splash back 13 is provided with ends 14and a top 15. This top is notched out as at 16 for the escape of coolingair from the chamber ll behind the range and splash back. Thisconstruction has similarity to the Fig. 2 construction in that the hotproducts of combustion from the broiling oven pass through an opening 11in the rear wall 18 of the oven into a flue l9 behind the range. Thisflue is in a plane forward of the splash back and communicates with thedeflector box or housing 80 through an opening 8| provided in theworking top portion of the range. This box is provided at its front withlouvers 82 for deflecting the hot products of combustion forwardly anddownwardly.

The lower end 83 of the flue I9 is open to communication with the airchamber l1 and consequently if the louver openings 82 of the box 80should become clogged or closed by a towel, dish cloth or some likeinstrumentality the hot products of combustion could in this emergencypass downwardly through the open lower end of the flue into the chamberI1 and escape through the notches 16 in the top 15 of the splash back.This featnre'I call a line relief" and is the feature previouslymentioned as being. one which could be incorporated into the other formsof the invention with very minor modifications of the flue constructionsillustrated in those forms.

In the constructions illustrated in Figures 3 to 5 and 8 and 9 of thedrawings the flues are not illustrated as having insulated rear walls.Insulation of these walls can be eliminated if desired as the aircirculating through the chamber I1 is sufficient to overcome'any flrehazard.

It is to be understood that the air inlet need not necessarily bepositioned at the from; of the range but could be in the end wallsthereof or otherwise disposed in any manner which would provide air foraccomplishing the hereinbefore enumerated functions.

In Figs; 10 and 11 a slightly different form or model of the range isillustrated. Like the Fig. 3 construction the range is a divided workingt'op type having working top portions 85 and 86 at the opposite sides ofthe cooking top portion 81. The splash back 88 closes in the chamber llbehind the range by reason of having a rearwardly extending top portion99 and end portions 90. The broiling and baking ovens vent their hotproducts of combustion through openings 9| in the table top workingportions which openings are covered by suitable grids 92. The manner inwhich the ovens are connected to these grid covered outlet openingsappears in Fig. 11 of the drawings in which it will be seen that theovens are provided in their tops with an outlet opening 93 communicatingwith a flue box 94 having an extending flue portion 95 connecting thebox with the aforementioned opening 9 I. In this construction the ovenflue outlets lie in a plane forward of the front of the splash backplate and air for the cooking top burners within the cooking top burnerchamber 5 can pass freely from the air chamber l1 behindthe range intosaid cooking top burner chamber through the open rear end thereofbetween and around the flue boxes 94.

The Fig. 12 construction illustrates a'modifled manner of connecting theovens with the openings 9| in the table top working surfaces of therange. In this instance the ovens have outlet openings 96 in their rearwalls from which flue conduits 91 extend upwardly in the air chamber l'lbehind the range and have their upper ends extending forwardly as at 99for connection with flue boxes 99 in the cooking top burner chambers Iwhich flue boxes have open upper ends connected to the outlet openings9| in the table top working portions of the range. In this constructionthe portions of the flue outlet conduit which are behind the range liein a plane forward of the front of the splash back plate 88. Air isadmitted to the cooking top burners in the manner described in respectto the Fig. 10 construction.

In the constructions illustrated in Figs. 10 to 12 inclusive air cancontinuously circulate upwardly through and outwardly from the airchamber I! by passing into the open rear end of the cooking top burnerchamber and escaping through the cooking grid constituting the cookingtop portion 81 of the ranges or if preferred an opening can be placed inthe top, front or end walls of the splash back to permit the escape ofair from the chamber [1.
